## What this rule covers
Amazon restricts or prohibits some products, categories, and claims. Requirements can vary by marketplace, category, fulfilment method, and the product's ingredients, materials, or intended use.
## Why sellers should care
A product that cannot be sold or has not received required approval can create listing removal, inventory, and account-health risk after money has already been committed to sourcing or FBA.
## Safer operating practice
Screen a product before placing inventory. Check current category requirements in Seller Central, identify any approval or documentation requirement, and retain evidence with the product record.
## Important note
Do not rely on a supplier statement or a previous listing alone. Amazon's current category and marketplace requirements take priority.
